CHARLES REAFSTAHL, OF PULLMAN, ILLINOIS.
SIDE SPRING FOR MOLDING-MACHIN'ES.
SPECIFICATION forming part of Letters Patent No. 354,229, dated December 14, 1886.
Application filed July 2l, 18:16. Serial No. 208,652. (No model.)
To all whom, t may concern:
Be it known that I, CHARLES REAEsTAIIL, a citizen of the United States, residing at the village of Pollina-min thccounty of Cook and State of Illinois,ha\'e invented a certain new and useful Improvement in Side Springs for MoldingMachines, which I desire Io protectby Letters Patent of the United States, and of which the following is a specication.
Heretofore it has been usual tov adjust the pivotal rod upon which the side spring is mounted by means of a set-screwa device which rapidly wears, besides being liable to displacement.
My invention has for its object to replace the set-screw by a durable coutrivance which will retain the arm fully in place without danger of displacement.
In the drawings annexed and forming part of this specification, Figure l is a side view of my device as it appears when attached to the operating-table, and Fig. 2 is a view ot' the same taken from below.
The table A has projecting above it a guidepiece, B, against which the strip of wood to be passed through the Inoldingmachine is pressed by the adjustable side spring, C, mounted in or attached to a pivotal rod, D, passng'down through a circular hole in the table. The arm G, as shown in the drawings, passes through a slot in the upper part of the rod D, and is held in place by a setscrew, E, in the upper end of the rod.
The rod D has in one of its sides a groove, G, extending from near itstop to its other end, and a lug, H, attached to a circular collar, I, iitted to the rod D, and through which the latter passes, tits into thedgroove and prevents the rod from turning, unless it carries with it the collar I. This collar is held against the .lower surface of the block K, attached to the under side of the table, by two lugs, J J, and the point of a spring-pawl, L, pivoted to the block, and is free to revolve in either direction, except when prevented by the engagement of the said pawl with a ring, M, of ratchet-teeth, attached to the under side of the collar or formed in one piece with the collar. The
pawl is pressed against the teeth of the ratchet by a spring, N, and. a handle, O, is provided ,to enable the operaorto pull the pawloutand release the rod D, and consequently arm C. The slot G permits therod to slide vertically, so as to adjust the arm C to blocks or pieces of material of various sizes. After the block has been placed upon the table and the rod D has been vertically adjusted to the proper height, it is turned so as to cause the end of the arm C to press against the block with the proper degree of pressure, where it is held by the engagement ot' the point of' the pawl with the ratchet.
The upper end of rod D is squared, asshown at F, for the application of a wrench for turning it.
This device, besides being more durable and certain in its action than the set-screw, is lnore readily and quickly set. Y
I wish it understood that I claim all the equivalents of the particular construction shown, as well as those constructions. Various'fornis might readily be given to the collar I and to the several parts, tongue D, and groove G, and the parts of the pawl andratchet device might be transposed each with reference to the other, respectively, and Inauy other changes might readily be Inade from the specic construction sh own,withont departing from my invention.
I claim- 1. The combination,with the guidepiece B, of the arm C, the rod D, carrying the same,
said rod beingprovided with a slot, G, the
collar I, provided with lug H and ring of ratchet-teeth M, and pawl L, substantiallT as and for the purpose set forth.
2. The combination of pressure-arm C, rod D, collar I, a tongue-andgroove connection being provided between said collar and said rod, and a pawland-ratchet device for con trolling the position of said collar.
